摘　　要：通过分析现有煤矿井下低压漏电选择性保护系统的方案,设计了一种以单片机为检测、PLC200为系统控制核心,Wincc6.0作为上位机的新型远程低压选择性漏电保护方案,实现了具有漏电实时检测和保护且系统具有B/S结构,更好地满足信息化矿山的需要。重点是远程检测系统的构建方案,简要介绍了所利用的漏电保护原理和实现方法。通过工程现场实际系统的运行,实现了漏电保护的实时性、选择性、准确性和远程检测。Through analysis of existing selective underground low voltage leakage protection system program, we designed the system by a single-chip microcomputer, PLC200 for the system control center and Wincc6.0 as a new type of PC remote low-voltage selective protection program. It can implement leakage detection and protection with real-time and the system has the B/S structure, so as to better meet the information needs of mine. This article focuses on long-range detection systems proposed, and briefly introduces the use of leakage protection principle and method. By the practical operation of this system, it realizes real-time leakage protection, selectivity, accuracy and long-range detection.
